The Study And Application Of High-precision Aeromagnetic Survey To Iron Ore Detection In Crisi Mines Of Daye

This paper presents systemic research for the high-precision aeromagnetic survey in search for deep-buried minerals in crisis mines of Daye.First,this paper expatiates the technique of aeromagnetic survey, status quo of applicaton and study to the technology in search for minerals. By the way, it sums up the advanced hardware and software of aeromagnetic survey, investigates the status quo of applicaton of this technology, and give more analysis of researching of the method to detection minerals.Second,this paper is the first to bring forward the notion of high-precision aeromagnetic survey. t summarizes the advantage of high-precision aeromagnetic survey and has a deep research of the data processing and transformation methods of potential fields on an arbitrary surface, calculation of residual signal ,the depth of target to detection,the method of 2.5-D inversion. An up-to-the-minute interactive man/computer inversion 3-D aeromagnetic anomalous bodies with arbitrary shaped.Last, the above-mentioned method belongs to this paper, which we used to detect the deep-buried minerals in crisis mines of Daye. We forecasted the position of the unbeknown mine , putted forward five drill to notarize the veracity of inversion calculation and reckoned the Resources about the mine of Daye.
